The Ground Segment for Chandrayaan-1 comprises of three major elements: the Ground Station Network including the Indian Deep Space Network (IDSN), Mission Operations Complex (MOX) and Indian Space Science Data center (ISSDC). This trio of ground facility ensures the success of the mission providing to and fro conduit of communication, securing good health of the spacecraft, maintaing the orbit and altitude to the requirements of the mission and conducting payload operations. The ground segment is also responsible for making the science data available for the Payload Scientists along with auxiliary information, in addition to archiving of payload and spacecraft data. Payload Operation Centers ( POCs) also form a part of the Ground Segment.
